The Twin Towers were part of a seven-building complex in Lower Manhattan, New York City, that formally opened on April 4th, 1973, and lasted until the September 11th, 2001, terrorist attacks. The Twin Towers consisted of one World Trade Center and two World Trade Centers. The original 1,381 feet (427 m) of Broadway between Liberty and Vesey Streets was renamed Freedom Plaza in 2011 after being renovated at a cost of $10 million.
Construction on the Twin Towers began in 1972 and they were completed four years later at a cost of $140 million. The buildings were designed by Skidmore, Owings & Merrill with Edward Durell Stone as lead architect. The complex was called "New York's architectural masterpiece" by then Mayor John Lindsay and was praised for its use of steel instead of stone or brick for its exterior. The main lobby of each tower had an enormous sculpture of alternating bands of gold and silver glass called the "Twin Towers Clock". It took six men five months to create this piece which was commissioned by American Airlines and manufactured by F. Schreiber & Co. of Allentown, Pennsylvania.
The Twin Towers were the world's first high-rise buildings to be constructed from reinforced concrete with interned columns inside to support the heavy floors. The upper floors contained offices and apartments while the lower floors were taken up by parking garages for 2,700 cars.
